woodcutting.speeds.

ok well my woodcutting is 81 and im wondering on some speeds. any type of tree above oak is what im looking for. things im looking for:
~ Avg minutes for full load.
~ How much faster one level is over another on a certain tree.
~ Anything else i can think of.
~ thankyou in advance.

i am currently getting some results on yews just gotta find myself a good world [ f2p atm ]
.~ load#1 = 15mins. this was with one other person woodcutting and there was 2 trees / rune woodcut axe.
.~ load#2 = 14 minutes. this was with 2 other people and once again 2 trees.
.~ load#3 = 12 minutes. 1 other person. 2 trees.
.~ load#4 = 14 minutes 3-4 other people, 2 trees.
average time taken is 13.75 minutes.
p.s a full load for me = 27 because im not yet 40 att .
hope this helps and im loking for more people to post results if you happen to be woodcutting.
